Question

A rectangular tablecloth measures 84 in. by 60 in. What length of lace is required to trim the edges of the cloth?

Answer 1

`288 \: \: in`

x

Explanation:

To find the length of the lace we have to simply find the perimeter of the table cloth.

Formula to to find the perimeter of a rectangle is,

`perimeter = 2(length + width) \\`

In this question , they have already given the length and the width of the table cloth

Length = 84 in

Width = 60in

Let's solve now

`p = 2(l + w) \\ = 2(84 + 60) \\ = 2 * 144 \\ = 288 \: in`

Hope this helps you.

Let me know if you have any other questions :-):-)

Answer 2

We have to find perimeter

• L=84in
• B=60in

`\\ \sf\longmapsto Perimeter=2(L+B)`

`\\ \sf\longmapsto Perimeter=2(84+60)`

`\\ \sf\longmapsto Perimeter=2(144)`

`\\ \sf\longmapsto Perimeter=288in`
